A client with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?

A.

For long-term control of normal eye pressure.

B.

Until a smaller angle can be restored.

C.

For long-term control of pain and swelling.

D.

Until the excess pressure is reduced.

Answer and Explanation

The Correct Answer is A

Choice A rationale

 

For long-term control of normal eye pressure is the accurate response. Open-angle glaucoma is a chronic condition that requires ongoing treatment to maintain normal intraocular pressure and prevent further damage to the optic nerve. Eye drops are typically used for life to manage the condition.

 

Choice B rationale

 

Until a smaller angle can be restored is not accurate because open-angle glaucoma does not involve a change in the angle of the anterior chamber. The goal of treatment is to lower intraocular pressure, not to restore the angle.

 

Choice C rationale

 

For long-term control of pain and swelling is not accurate because open-angle glaucoma primarily involves increased intraocular pressure and optic nerve damage, not pain and swelling. The goal of treatment is to lower intraocular pressure.

 

Choice D rationale

 

Until the excess pressure is reduced is not accurate because open-angle glaucoma requires ongoing treatment to maintain normal intraocular pressure. Stopping treatment once pressure is reduced can lead to a recurrence of elevated pressure and further damage.

Correct Answer is B

Explanation

Choice A rationale

An increase in B-lymphocytes and IgM is not how HIV suppresses the immune system. B-lymphocytes are responsible for producing antibodies, and IgM is a type of antibody. HIV primarily affects T-lymphocytes, specifically helper T-cells (CD4 cells), rather than B-lymphocytes.

Choice B rationale

The destruction of helper T-cells and CD4 cells is the primary mechanism by which HIV suppresses the immune system. HIV targets and infects these cells, leading to their depletion. Helper T-cells play a crucial role in coordinating the immune response, and their loss results in a weakened immune system, making the body more susceptible to infections and diseases.

Choice C rationale

A deficiency of cytotoxic T cells is not the primary mechanism by which HIV suppresses the immune system. Cytotoxic T cells (CD8 cells) are involved in directly killing infected cells, but the main impact of HIV is on helper T-cells (CD4 cells), which are essential for orchestrating the immune response.

Choice D rationale

The proliferation of suppressor T-cells is not how HIV suppresses the immune system. Suppressor T-cells (regulatory T cells) help regulate and control the immune response, but HIV primarily affects helper T-cells (CD4 cells), leading to their destruction and a weakened immune system.

Correct Answer is B

Explanation

Choice A rationale

Obtaining vital signs every 2 hours is important for monitoring the patient’s overall condition, but it is not the immediate priority following the surgical removal of glass from the eye.

Choice B rationale

Providing an eye shield to be worn while sleeping is crucial to protect the eye from injury and promote healing after the surgical removal of glass. This intervention helps prevent accidental rubbing or pressure on the eye.

Choice C rationale

Teaching a family member to administer eye drops is important for ongoing care, but it is not the immediate priority following the procedure. The immediate focus should be on protecting the eye and ensuring proper healing.

Choice D rationale

Encouraging deep breathing and coughing exercises is important for preventing respiratory complications, but it is not directly related to the immediate care of the eye following the surgical removal of glass.
